A recording tape cartridge having a recording tape; a leader member attached at the top of the recording tape; a single reel on which the recording tape is wound; a housing holding the reel rotatably and having an opening from which the tape is wound out and a holding portion adjacent to the opening; and an urging member urging and securing the leading member at the holding portion when the recording tape is taken back in the housing; the urging member having a pressing portion formed continuously in the axial direction of the leading member and contacting both ends of the leading member when the leading member is held at the holding portion. Equal force is applied to the both ends of the leading member. Therefore, the leading member does not slant and a chucking member of the tape drive securely chucks the leader member.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A recording tape cartridge comprising: a recording tape; a leader member attached at an end of the recording tape and extending in a width direction of the recording tape; a single reel on which the recording tape is wound; a housing for holding the reel rotatably and including a take-up opening from which the tape is taken up and a holding portion formed adjacent to the opening; and an urging member for urging the leading member and securing the same at the holding portion when the recording tape is taken back in the housing; the urging member including a pressing portion formed continuously in the axial direction of the leading member and contacting both ends of the leading member when the leading member is secured at the holding portion.
2. The recording tape cartridge of claim 1 , wherein the leader member is a leader pin.
3. The recording tape cartridge of claim 2 , wherein the holding portion is a pair of recessions formed at a position of an inner wall of the housing adjacent to the take-up opening so as to face to each other with the recording tape therebetween.
4. The recording tape cartridge of claim 3 , wherein the urging member is a plate spring.
5. The recording tape cartridge of claim 4 , wherein the plate spring is formed of metal.
6. The recording tape cartridge of claim 5 , wherein the plate spring has a frame-shape and an opening in a central portion thereof.
7. The recording tape cartridge of claim 6 , wherein the recording tape is a magnetic tape.
8. The recording tape cartridge of claim 4 , wherein the plate spring is formed integrally with the housing.
9. The recording tape cartridge of claim 8 , wherein the recording tape is a magnetic tape.
10. The recording tape cartridge of claim 2 , wherein the urging member is a plate spring.
11. The recording tape cartridge of claim 10 , wherein the plate spring is formed of metal.
12. The recording tape cartridge of claim 11 , wherein the plate spring has a frame-shape and an opening in a central portion thereof.
13. The recording tape cartridge of claim 12 , wherein the recording tape is a magnetic tape.
14. The recording tape cartridge of claim 10 , wherein the plate spring is formed integrally with the housing.
15. The recording tape cartridge of claim 14 , wherein the recording tape is a magnetic tape.
16. The recording tape cartridge of claim 1 , wherein the urging member contacts the leader member at at least two portions thereof, said portions being connected to each other in the axial direction of the leading member.
17. The recording tape cartridge of claim 16 , wherein the leader member is a leader pin.
18. The recording tape cartridge of claim 17 , wherein the holding portion is a pair of recessions formed at a position of an inner wall of the housing adjacent to the take-up opening so as to face to each other with the recording tape therebetween.
19. The recording tape cartridge of claim 18 , wherein the urging member is a plate spring.
20. The recording tape cartridge of claim 19 , wherein the plate spring is formed of metal.
